#2069-Dynamic row object fields not accessible

I am currently using dynamic list rows to show bookings to the user, where each item in the array contains multiple fields.

i successfully displaying the bookings in the Row block. In the Row configuration, we’ve set:

Row Generation Method: Dynamic.

Custom Field for Dynamic Rows: #available_booking# (mapped available_booking with raw response ).

Save Selection to Custom Field: selected_booking.

Key/Index for Saved Value: (left empty) [because i am unable to add more than 1 value in it].

Now, after a user selects a row, I want to access the whole object of that property in the next message. But unfortunately, the value isn't rendering. It just returns the raw placeholder instead of the actual data.

Am i missing something in how we’re saving or accessing the selected object?
